Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image capture devices face challenges in combining images from external devices due to varying data sizes, which can affect image quality, either through delays or reduced quality when adjusting image resolutions.
Innovation Solution
A communication apparatus with a wireless communication unit, image capturing unit, and control unit that determines the resolution of captured images and requests corresponding resolutions from external devices, allowing for efficient image combination by adjusting sub-image data sizes based on main-image data resolutions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the data size of the sub image to be received is large, then the image quality of the sub image is maintained, but the amount of data associated with the communication becomes large causing delay or failure in image reception
Solution Approach 1:
The patent applies dynamics by making the sub-image resolution adjustable based on real-time communication conditions. The control unit dynamically changes the resolution of the sub image captured by the external apparatus according to the communication speed and data transmission status, allowing the system to adapt between high quality (when communication is fast) and low delay (when communication is slow), thus resolving the contradiction between maintaining image quality and reducing reception delay
Solution Approach 2:
The patent changes the resolution parameter of the sub image based on communication conditions. When communication speed is high, the sub image is captured at higher resolution to maintain quality; when communication speed is low, the resolution is reduced to decrease data size and avoid reception delay. This parameter adjustment directly addresses the contradiction between image quality and reception timing
2Productivity
If the data size of the sub image to be received is small, then the communication efficiency is improved, but the image quality of the combined image is lowered when the sub image needs to be enlarged
Solution Approach 1:
The patent applies preliminary action by capturing the sub image at high resolution before communication occurs. The external apparatus captures the sub image at the same resolution as the main image, ensuring high quality is preserved in the original data. Then, during communication, the control unit adjusts the transmitted resolution based on communication conditions, but the high-resolution original is already captured, allowing quality to be maintained when needed while enabling efficient transmission when communication is slow
3Quantity of substance
If the sub image is adjusted to a size smaller than the main image after reception, then the communication data size is reduced, but the image quality is affected by the size adjustment process
Solution Approach 1:
The patent inverts the conventional approach by not reducing the sub image size after reception, but instead capturing it at the appropriate size from the beginning. The control unit requests the external apparatus to capture the sub image at a resolution matching the main image, then adjusts the resolution before transmission based on communication conditions. This inversion avoids post-reception resizing operations that would degrade quality, as the image is captured at the correct resolution from the start

AI summary
An apparatus, when it is determined that a resolution of a captured image is higher than or equal to a predetermined resolution, transmits, to an external apparatus, a first request for an image of a resolution corresponding to a resolution higher than or equal to the predetermined resolution, and when it is determined that the resolution of the captured image is not higher than or equal to the predetermined resolution, transmits, to the external apparatus, a second request for an image of a resolution corresponding to a resolution lower than the predetermined resolution, performs control to sequentially receive images that are sequentially captured by the external apparatus, and performs control to combine the images that are captured by the external apparatus with the images that are sequentially generated by the image capturing, and sequentially display the combined images.
